What is the linear function defines the following Arithmetic Sequence? - 5, - 3, - 1, 1, 3, ...

a. an = - 5 + 2 (n - 1)

b. an = - 5 - 2 (n - 1)

c. an = 5 - 2 (n - 1)

d. an = 5 + 2 (n - 1)

an = - 5 + 2 (n-1)

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1 + d (n-1)

where a1 is the first term and d is the common difference

a1 = - 5 since it is the first term in the sequence

d = term 2 minus term1

= - 3 - (-5)

= - 3+5 = 2

an = - 5 + 2 (n-1)
